Description

  The present invention relates to a stand-type charging device used for charging an electric vehicle, a plug-in hybrid car, or the like.

  In the future, electric vehicles and plug-in hybrid vehicles, which are expected to spread rapidly, require a charging device for an on-board battery. Since such a charging device is used with a charging cable connected, the operability is poor at a very low position, and it is desirable to install it at a certain height. Therefore, conventionally, a wall-mounted type and a vertical type have been proposed. It is assumed that the wall-mounted charging device is mainly installed on the wall surface of a parking lot for home use, and the vertical charging device is mainly installed in a public space such as a supermarket or a coin parking lot.

  As a vertical charging device, a cabinet-shaped device has been proposed as shown in Patent Document 1. This is a single cabinet with a single charger. However, such a cabinet-shaped device requires a wide installation space similar to that of a gas station. Therefore, in consideration of the future popularization of electric vehicles and the like, a stand-type charging device that can be installed in a narrower space is required.

  However, if a large number of stands are installed in the charging space as many as the number of vehicles, there is a risk that the vehicle will accidentally touch these stands when driving the vehicle in and out of the charging space. Such a contact or collision not only damages the automobile, but also causes a serious trouble because the power supply line housed in the charging stand is disconnected or short-circuited.

Japanese Patent Laid-Open No. 11-122714

  The present invention solves the above-mentioned conventional problems, reduces the number of stands installed, facilitates taking in and out of a car, and further enables charging of a car for a space for charging at the same time. It is intended to provide.

In order to solve the above problems, the stand-type charging device of the present invention is provided with a plurality of independent charging devices on the top of a single stand erected on the ground or the floor , and the stand A hollow portion is formed in the center of the battery, and an electric wire for supplying power to each of the charging devices is wired through the hollow portion .

  A plurality of independent charging devices are arranged side by side on the top of the stand, a plurality of independent charging devices are arranged back to back on the top of the stand, and a plurality of independent charging devices are provided on the stand. The form etc. which are radially arranged on the upper part of can be taken.

  According to the stand-type charging device of the present invention, it is possible to charge a plurality of electric vehicles or the like by a plurality of independent charging devices. In addition, since the number of stands is greatly reduced, the possibility of contacting or colliding with the stands when the vehicle is taken in and out of the charging space is reduced. In addition, since the same charging device is not provided with a plurality of outlets, charging is performed individually, and an accident in which a plug of another automobile is accidentally pulled out at the end of charging can be prevented.

  In particular, if a plurality of independent charging devices are arranged back to back on the top of the stand or adopt a configuration in which they are arranged in a radial manner, the distinguishability is improved and the connection destination of the charging cable is not mistaken.

1 is an overall perspective view showing a first embodiment of the present invention. It is an expansion perspective view of the stand part in a 1st embodiment. It is a whole perspective view which shows the 2nd Embodiment of this invention. It is an expansion perspective view of the stand part in 2nd Embodiment.

Preferred embodiments of the present invention are shown below.
1 and 2 show a first embodiment of the present invention. As shown in FIG. 1, the stand-type charging device of the present invention is provided at the center of two charging spaces P1 and P2. In FIG. 2, 1 is a bar-shaped or column-shaped stand erected on the ground or floor, and 2 is two charging devices provided at the upper end thereof. In this embodiment, the stand 1 is constructed by assembling back-to-back groove steels having a U-shaped cross section. The power supply electric wire passes through a hollow portion formed in the center of the stand 1 and reaches each charging device 2. By installing the charging device 2 at a high position above the stand 1 in this way, a charging operation can be performed without bending down.

  Each charging device 2 is in the form of a small box provided with a door 3 and a roof 4, and at least a charging control device and a charging outlet are accommodated therein, and the user opens the door 3. Perform the charging operation. The charging device 2 can be provided with a charging timer, a charging device, a locking device, and the like. The two charging devices 2 are independent from each other and are installed back to back. It goes without saying that one charging device 2 is used to charge a car parked in the charging space P1, and the other charging device 2 is used to charge a car parked in the charging space P2. .

  Reference numeral 5 shown in FIG. 2 denotes a charging cable connected to a charging outlet inside the box of the charging device 2, and a charging cutoff device 6 called CCID is connected to a portion near the base. In this embodiment, the charging cable 5 is always connected to the charging device 2, but the charging cable 5 can also be loaded on a car, in which case the charging cable 5 is always connected to the charging device 2 side. There is no need to keep it. If the charging cable 5 and the charge interrupting device 6 can be accommodated inside the grooved steel constituting the stand 3 as shown in FIG. 2, there is an advantage that the appearance is good and damage can be prevented. In addition, since the charge interruption | blocking apparatus 6 has considerable weight, it is preferable to provide an exclusive holder and to reduce the tensile load concerning the charging cable 5. FIG.

  2 is a charging gun at the tip of the charging cable 5, which is connected to a charging terminal on the automobile side. In this embodiment, gun holders 8 are provided at two locations on the top of the stand 3 so that the charging gun 7 at the tip of the charging cable 5 extending from each charging device 2 can be hooked.

  Since the charging cable 5 reaches several meters in length, a cord reel can be provided for winding after charging. In this embodiment, a concave groove 9 extending in the left-right direction is formed on the roof 4 of the charging device 2 so that the charging cable 5 can be hooked in a wound state.

  In the stand-type charging device having such a structure, it is only necessary to set up the stand 3 at a ratio of one to two in the parallel parking lot, and it is difficult to get in and out of the car. There is also an advantage that the charging device 2 to be used is easy to understand.

  3 and 4 show a second embodiment of the present invention. As shown in FIG. 3, a stand-type charging device is provided at the center of the charging spaces P1 to P4 for four vehicles. As shown in FIG. 4, the stand 1 of this embodiment is constructed by assembling back-to-back groove-shaped steels having a U-shaped section in four directions. And the four charging devices 2 are radially installed in the upper end part toward 4 directions. Similar to the first embodiment, these charging devices 2 are also of a small box shape, and at least a charging control device and a charging outlet are accommodated therein. Each charging device 2 is independent from each other, and four gun holders 8 are installed in the vicinity of the charging device 2.

  The stand-type charging device having such a structure is suitable for installation in a place with a lot of parking space such as a supermarket, and it is sufficient to set up the stand 3 at a ratio of one to four, which is an obstacle to taking in and out of a car. Hard to become. In FIG. 4, the four charging devices 2 are arranged at the same height at the upper end of the stand 1, but the heights may be changed alternately.

  In the embodiment described above, the charging devices 2 are arranged in different directions, but a plurality of charging devices can be arranged vertically or horizontally in the same direction on the top of the stand 1. The structure of the stand 1 is not limited to that of the embodiment, and H-shaped steel may be used, or a hollow column such as a cylinder or a prism may be used.
